Description
The 74ALS93 4-bit binary counter is fabricated using a 2µm 40V bipolar process. The device comprises two 4-bit ripple type counters consisting of four master-slave flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. Each section has independent clock (CK) & asynchronous master reset (R0) inputs. Counter state change is triggered by a high-to-low transition on the clock. Each section can be used separately or tied together (Q to CK) to form BCD or modulo-16 counters. 

FEATUREs:
◾ Low Power Consumption
◾ Input Clamp Diodes Limit High Speed
   Termination Effects
◾ Direct drop-in replacement for obsolete
   components in long term programs.
